Campaigners seeking to have the ban on Iran's main opposition party lifted by the Home Secretary received encouraging news this week. The People's Mojahedin Organisation of Iran was proscribed under anti-terrorism legislation in 2001 because of allegations that it had links to terrorists. But, as I noted two weeks ago, 1,300 lawyers have signed a declaration calling on the Government to distance itself from the Iranian regime by lifting the ban. On Tuesday, the lawyers were joined by 279 MPs and 126 peers of all parties, who said the ban was "the most important impediment" to democratic change in Iran.
